Case 700-B tach/speedometer cables

t17wilson · Mar 30, 2020

I'm working on my 700-B Pounds Orchard tractor and not sure about the tachometer and speedometer cables. Both are broken, as in only a few inches are sticking up out of the side of the engine and the transmission housing. I've moved the "nut" at the top of the transmission housing for the speedometer cable and it will loosen. Looking at the parts manual I don't understand how they attach and haven't found the replacement cables yet (I know, I need to call John Saeli!) Is there anything bad that will happen if I unscrew it completely? I really don't want to take the top off the trans and surely don't want to go into the base to connect to the tach drive there unless I have to. Here is a picture of what's left sticking out of the transmission housing. Thanks for your help!

The tranny cable is just a long piece of cable with a square end to drive from the drive gear that drives off the front of the ring and pinion shaft, it is guided down by a tube that serves as its sheath till it gets down to the drive. You cannot get in any trouble taking it out but it may be rusted if moisture has worked down the cable.

To add to what mEl has said, use a six sided socket or a line wrench to remove the nut as the thin walls will distort with an open end wrench. PB Blaster/Liquid Wrench soak a day if it doesn't readily give.
